=head1 list-php-ini.pl

Show PHP variables for some or all domains.

This command can be used to list the value of a PHP configuration variable
(set in the php.ini file) for one or many virtual servers at once. The
servers to update can be selected with the C<--domain> or C<--user> flags,
or you can choose to modify them all with the C<--all-domains> option.

If your system supports multiple PHP versions, you can limit the changes
to the config for a specific version with the C<--php-version> flag followed
by a number, like 7.4 or 8.2.

The variables to show are set with the C<--ini-name> flag, which can be
given multiple times to list more than one variable.
